Figure 3From: Normalization of two-channel microarrays accounting for experimental design and intensity-dependent relationshipsSummary of simulated t-statistics. Comparison of t-statistics (averaged across 100 simulations) and true mean differences after MA (left), ANOVA (middle), and eCADS (right) normalization. Black points represent genes for which the sign of differential expression has not been preserved. Plots for MA show systematic shift, indicating bias.Back to article page
